There is no indication anywhere in the Bible that God created any humans other than Adam and Eve. In Genesis 2 we read, “This is the account of the heavens and the earth when they were created, in the day that the LORD God made earth and heaven. Now no shrub of the field was yet in the earth, and no plant of the field had yet sprouted, for the LORD God had not sent rain upon the earth, and there was no man to cultivate the ground. But a mist used to rise from the earth and water the whole surface of the ground. Then the LORD God formed man of dust from the ground, and breathed into his nostrils the breath of life; and man became a living being. The LORD God planted a garden toward the east, in Eden; and there He placed the man whom He had formed” Then the LORD God said, “It is not good for the man to be alone; I will make him a helper suitable for him.” “So the LORD God caused a deep sleep to fall upon the man, and he slept; then He took one of his ribs and closed up the flesh at that place. The LORD God fashioned into a woman the rib which He had taken from the man, and brought her to the man” (Genesis 2:4–8, 18, 21–22).
Notice that it says “there He placed the man whom He had formed.” Not the “men,” just the one “man.” And this man was alone (v. 18) so God made a woman out of his rib to be his companion. All other human beings have descended from these two original people. The two main reasons why this question usually comes up are: (1) Cain’s wife, and (2) the origin of the different races. If the only people on the earth were children of Adam and Eve, who did Cain marry and how did we get all the different races of people with their different skin colors from just two people? For answers to these issues, please read “Who was Cain’s wife?” and “What is the origin of the different races?”
